Tornen els experiments a l’Escola 16 de Febrer!!!<\/p>\n

Us presentem una cr\u00f2nica detallada dels sis experiments que hem portat a terme al llarg d’aquest inici de curs amb la intenci\u00f3 de fomentar l’inter\u00e8s per la ci\u00e8ncia i inspirar futurs cient\u00edfics.<\/p>\n

Experiment 1: VIURAN LES HEURES?<\/p>\n

Hem plantat talls d’Heures amb tres possibles hip\u00f2tesis. Viuran amb aigua, aigua i terra o nom\u00e9s terra. Haurem d’esperar per veure quines plantes arrelaran.<\/p>\n

Aix\u00f2 \u00e9s possible amb moltes esp\u00e8cies d’herbes. Aquesta pr\u00e0ctica \u00e9s coneguda com a “esqueixar” o “fer arrels d’aigua”. Algunes herbes, com el menta, el roman\u00ed i la s\u00e0lvia, s\u00f3n especialment propenses a arrelar-se en aigua.<\/p>\n

Experiment 2: PLASTILINA CASERA.<\/p>\n

Hem creat plastilina casera amb oli, farina, sal, colorant i aigua. Hem donat import\u00e0ncia a la barreja de materials ja que ens en pot donar de nous.<\/p>\n

Aquest experiment ens ha perm\u00e8s explorar les diferents propietats de les receptes de plastilina casolana. Hem apr\u00e8s com els ingredients i les seves proporcions poden influir en la textura i la capacitat de modelar-la. Aix\u00f2 pot ser \u00fatil per a futurs projectes d’art i manualitats.<\/p>\n

\"\"<\/p>\n

Experiment 3: QU\u00c8 \u00c9S EL FLUX LAMINAR?<\/p>\n

S’anomena aix\u00ed el moviment d’un fluid (en aquest cas, l’aigua) quan aquest \u00e9s de manera ordenada i suau; en l\u00e0mines paral\u00b7leles i sense barrejar-se. En aquest experiment, en col\u00b7locar la cinta a\u00efllant i punxar el globus, cada part\u00edcula de l’aigua segueix una traject\u00f2ria anomenada \u00abl\u00ednia de corrent\u00bb, pareix que l’aigua estigui congelada.<\/p>\n

\"\"<\/p>\n

Experiment 4: LA M\u00c0GIA DE LA TENSI\u00d3 SUPERFICIAL.<\/p>\n

La tensi\u00f3 superficial de l\u2019aigua \u00e9s una for\u00e7a que fa l\u2019aigua a la seva superf\u00edcie i que permet que alguns insectes s\u2019hi puguin posar a sobre sense esfor\u00e7ar-se.<\/p>\n

En el cas del nostre experiment, hem posat un fil sobre la bombolla i, al trencar la tensi\u00f3 superficial de dintre, podem observar que es forma una circumfer\u00e8ncia exacta.<\/p>\n

\"\"<\/p>\n

Experiment 5: COM FUNCIONA UN ESPRAI?<\/p>\n

El Principi de Bernoulli relaciona la pressi\u00f3 amb la velocitat d\u2019un fluid. Ens diu que, si la velocitat d\u2019un l\u00edquid o un gas augmenta, la seva pressi\u00f3 disminueix. Amb aquest principi hem intentat que pugi l’aigua en forma d’esprai.<\/p>\n

\"\"<\/p>\n

Experiment 6: ELS CIRCUITS EL\u00c8CTRICS I L’ENERGIA.<\/p>\n

Experimentem amb els circuits el\u00e8ctrics: expliquem qu\u00e8 s\u00f3n els materials conductors i a\u00efllants, com es crea l’energia el\u00e8ctrica, quines energies s\u00f3n netes …<\/p>\n

Quan s’aconsegueix encendre la bombeta sempre s’escapa un somriure.<\/p>\n

Aviat en penjarem m\u00e9s. Esperem que us hagin agradat !!!<\/p>\n","protected":false},"excerpt":{"rendered":"
